Description

Paper guides for duplexer

The present invention relates to a duplex printing apparatus, and more particularly, to a paper guide for easily removing a jammed paper when a paper jam occurs on a conveyance path of a sheet for duplex printing.

1 is a schematic diagram showing an internal configuration of a duplex printing apparatus provided with a paper guide according to an embodiment of the prior art.

In the related art, as shown in FIG. 1, the paper 10 loaded in the paper feed cassette 20 is picked up by the rotation of the pickup roller 11, and the picked paper is transferred to the developing unit 30 along the feed path A. FIG. Move. The photosensitive drum 32 of the developer in which the electrostatic latent image is formed by the exposure unit 40 and the toner is developed, transfers the toner image on the paper 10, and the toner image transferred to the paper is the paper fixing roller 13. ) Is fixed to the paper surface as it passes between the heating roller 14 and the heating roller 14.

The paper passing through the fixing roller and the heating roller passes between the discharge rollers 15, and one end of the paper rotates the inversion guide 45 by the rotational force of the discharge roller. That is, the paper rotates the inversion guide, and in the case of single-sided printing, the paper is discharged to the outside through the outlet roller 16.

On the other hand, in the case of double-sided printing, one-sided printing as described above should be repeated once more. In this case, when the paper passes the reversal guide, a paper detection sensor (not shown) operates to detect the paper. Then, the outlet roller 16 is reversely rotated by the auxiliary motor provided separately, so that the paper is not discharged to the outside, and the upside down roller is inverted along the transfer path B formed on the lower side of the outlet roller with the upside down. ), And then passes through the driving roller 50 and the feed roller (52).

Then, the paper is passed between the upper paper guide 100 and the lower paper guide 101 is transferred to the pickup roller (11). At this time, the reverse feed roller and the drive roller is also rotated by the drive of a separate drive motor. The paper conveyed to the pickup roller is discharged to the outside through the image forming process as in the one-side printing.

However, when using the above method, the paper moving in the reverse feed path is caught between the upper paper guide 100 and the lower paper guide 101, or is caught between the drive roller 50 and the feed roller 52. In this case, in order to pull out the jammed paper, it is necessary to remove the paper cassette installed under the lower paper guide, and also to disassemble the main body of the duplexer by flipping the main body of the duplexer to remove the upper paper guide and the lower paper guide. There was a problem.

In order to solve the above problems, an object of the present invention is to provide a paper guide which can easily remove a jammed paper by removing the paper cassette when the paper jams on the reverse feed path in the duplex printing apparatus.

In order to achieve the above object, the present invention provides a duplex printing with an upper paper guide on a reverse feed path, a lower paper guide installed under the upper paper guide, and a paper cassette mounted under the lower paper guide. In the apparatus, the lower side paper guide extends upward from one side to form an inwardly curved side guide rail, and the other side of the lower paper guide is hinged and the other side combined with the lower paper guide is hinged upwardly And a paper jammed between the upper paper guide and the lower paper guide to remove the paper feed cassette and remove the jammed paper.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention relates to a duplex printing apparatus, and more particularly, to a paper guide for easily removing a jammed paper when a paper jam occurs on a conveyance path of a sheet for duplex printing.

Figure 2 is a perspective view showing a paper guide for easy jam removal according to a preferred embodiment of the present invention. As shown in FIG. 1, the paper guide of the present invention extends from one side to a lower paper guide 101 having a side guide rail 110 bent inward, and one side and a hinge 201 of the lower paper guide. The opposite side combined with the lower paper guide is composed of the hinge guide 200 is bent upward. In addition, the hinge guide extends from one side to form a side guide rail 110 bent inward.

Figure 3 is a side view showing the appearance of the paper guide in the paper feed cassette mounted state according to a preferred embodiment of the present invention, Figure 4 is a paper guide of the paper cassette in the detached state according to a preferred embodiment of the present invention Side view showing the state.

As shown in FIG. 3, the paper guide of the present invention is installed below the upper paper guide 100, and the main body of the paper guide is spaced apart from the lower surface of the hinge guide by a predetermined distance below the hinge guide 200 of the present invention. A locking projection 202 extending from the inner side is formed.

On the other hand, when the paper feed cassette 20 is mounted, the upper end portion of the paper feed cassette pushes up the bent portion of the hinge guide 200, so that the hinge guide is kept horizontally between the upper paper guide and the lower paper guide. The paper is fed.

When the paper is jammed between the upper paper guide 100 and the lower paper guide 101, the paper feed cassette 20 is removed. Then, as illustrated in FIG. 4, the hinge guide 200 rotates around the hinge 202 by its own weight, and the lower side of the hinge guide is caught by the locking protrusion 202. At this time, the user can insert the hand into the gap (C) between the hinge guide and the upper paper guide to remove the jammed paper.

5 is a side view showing a state of the paper guide attached to the leaf spring according to another embodiment of the present invention, Figure 6 is a state of the paper guide attached to the leaf spring according to another embodiment of the present invention is flipped The side view shown.

As shown in FIG. 5, a paper guide according to another embodiment of the present invention includes a lower paper guide 101 extending upward from one side to form a side guide rail bent inward, and one side of the lower paper guide. The opposite side coupled to the hinge 201 and coupled to the lower paper guide consists of a hinge guide 200 bent upward, and a leaf spring 210 having one side attached to the lower side of the lower paper guide and the lower side of the hinge guide, respectively. . In addition, the hinge guide 200 extends upward from one side to form a side guide rail 110 bent inward.

Since the upper end of the paper feed cassette pushes up the bent portion of the hinge guide when the paper feed cassette is mounted, the paper is conveyed between the upper paper guide and the lower paper guide while the hinge guide is kept horizontal.

On the other hand, when paper is jammed between the upper paper guide and the lower paper guide, the loaded paper cassette is removed. As shown in FIG. 6, when the bent portion of the hinge guide 200 is pulled downward, the hinge guide rotates about the hinge 201.

The hinge guide 200 does not open more than a certain angle by the leaf spring 210 attached to the lower side. At this time, the user can insert the hand between the gap between the hinge guide and the upper paper guide to remove the jammed paper.

After removing the jammed paper, when the user releases the hinge guide 200 which is being pulled down, the hinge guide rotates to the original position by the restoring force of the leaf spring 210.

As described above, the paper guide of the duplex printing apparatus according to the embodiment of the present invention has an effect of easily removing the jammed paper by removing only the paper cassette without disassembling the main body, even if the paper is jammed on the reverse feed path. There is.
